Abstract (en)
[origin: EP1591883A2] The device has a video controlling unit (3) giving a horizontal synchronization signal (H-sync) as a line synchronization signal (H-sync1) directly on one of two graphic displays (1,2). A line clock generator (4), producing another line synchronization signal (H-sync2) and giving out to the other display, is switched on between the unit (3) and the latter display. The signal (H-sync2) is pushed time to time against the signal (H-sync1). An independent claim is also included for a graphic displays controlling method.
